Ezekiel 33:2-6

“Son of man, speak to the sons of your people and say to them, ‘If I bring a sword upon a land, and the people of the land take one man from among them and make him their watchman,

and he sees the sword coming upon the land and blows the horn and warns the people,

then someone who hears the sound of the horn but does not take warning, and a sword comes and takes him away, his blood will be on his own head.

He heard the sound of the horn but did not take warning; his blood will be on himself. But had he taken warning, he would have saved his life.

But if the watchman sees the sword coming and does not blow the horn and the people are not warned, and a sword comes and takes a person from them, he is taken away for his wrongdoing; but I will require his blood from the watchman’s hand.’
